---++ Formatting Tokens Foswiki defines some standard special tokens that can be used to replace characters in some parameters - notably those to FormattedSearch and IfStatements - to defer evaluation of the parameter until later. These special tokens are often called "escapes", because they allow the character to "escape" from its normal meaning. %STARTINCLUDE%| =$n= or =$n()= | New line. Use =$n()= if followed by alphanumeric character, e.g. write =Foo$n()Bar= instead of =Foo$nBar= <blockquote class="foswikiHelp">%T% Most macros accept parameter strings which are split over multiple lines. This is usually more readable than using =$n= tokens. If you are familiar with [[VarSTARTSECTION][sectional includes]], you might also consider [[FormattedSearch#NestedSectionalInclude][nested sectional includes]] to hold the newline content outside of the parameter string entirely.</blockquote> \ <blockquote class="foswikiHelp">%T% Note that newline is _not_ a line break. The browser will wrap the lines together. If you require a line break, displaying the results on two lines, use =%<nop>BR%=. Or use two consecutive newlines to create a TML "Paragraph".</blockquote> | | =$nop= or =$nop()= | Is a "no operation". This token gets removed; useful for nested search | | =$quot= | Double quote (="=) (\" also works) | | =$percent= | Percent sign (=%=) (=$percnt= also works) | | =$dollar= | Dollar sign (=$=) | | =$lt= | Less than sign (=<=) | | =$gt= | Greater than sign (=>=) | | =$amp= | Ampersand (=&=) | | =$comma= | Comma (=,=) | %STOPINCLUDE% If you ever find yourself needing to escape an escape, you can use =$dollar= to escape the leading dollar, thus: =$dollarpercent=.
